Overview

3. Maintenance Features

The 8" Bench Grinder, Stock Number W50058, is a power tool designed for grinding and sharpening tasks. It is intended for use in a workshop setting and requires careful adherence to safety instructions and proper operating procedures.

Function Description

The primary function of the bench grinder is to remove material from workpieces using abrasive grinding wheels. It features two grinding wheels, one with 60 grit (for light material removal) and another with 36 grit (for heavy material removal), allowing for versatility in different tasks. The motor housing contains the electrical motor that drives the grinding wheels. The tool is equipped with an ON/OFF switch for controlling power.

Usage Features

The bench grinder is designed with several features to enhance its usability and safety. It includes wheel guards that cover the grinding wheels, protecting against accidental contact. These guards also provide access for routine maintenance. Spark guards are positioned to prevent hot sparks and debris from contacting the operator during use. Eye shields, which are protective see-through shields, further prevent loose debris from contacting the operator's eyes.

Tool rests are provided to support the workpiece being ground. These rests can be adjusted closer to the wheel as the wheel's diameter decreases due to wear, ensuring consistent support. The bench grinder must be securely mounted to a suitable workbench or work surface before operation, and mounting feet help to minimize vibration.

For electrical connection, the tool is equipped with a 3-prong grounding plug, which must be plugged into a matching 3-contact electrical receptacle to provide protection against accidental electrical shock. It is crucial not to modify the plug or remove the third prong. The tool is factory wired for 115V, 60 Hz operation and should be connected to a 115V, 15 amp branch circuit with a time delay fuse or circuit breaker.

When starting the grinder, users are advised to stand to one side to avoid any debris discharged toward the operator. Workpieces should be applied gently to the grinding wheel, as sudden impact can damage the wheel. Slight pressure is recommended when starting to grind, and excessive pressure on a cold wheel should be avoided.

Maintenance Features

Regular maintenance is essential for the safe and efficient operation of the bench grinder. Before any adjustments, part changes, or maintenance, the power switch must be in the "OFF" position and the tool unplugged from the electrical receptacle.

Grinding wheels are consumables and will wear down with use, becoming smaller, grooved, rounded, chipped, or loaded with foreign material. Cracked or damaged grinding wheels must be replaced immediately. When replacing a wheel, it is important to choose one with a safe rated speed as high as the RPM marked on the grinder's nameplate and with a 5/8" center hole. The maximum width for an 8" diameter wheel is 1". Users should carefully inspect new wheels for cracks before installation and ensure that the label or blotter on both sides of the grinding wheel is not removed. The spindle nut should be tightened just enough to hold the wheel firmly without excessive clamping force, which can damage the wheel.

The distance between the work rest and the grinding wheel must be periodically adjusted to 1/16" as the wheel wears. The wheel guards should also be kept in place and in proper working condition; operating the grinder with removed wheel guards is not recommended.

Cleaning the bench grinder should only be done when the power switch is in the "OFF" position and the tool is unplugged. Users should slowly turn the grinding wheels and inspect for damaged or trapped debris and dust buildup. A clean dry rag or brush can be used to remove debris. Flammable materials should never be used to clean the grinder.

The bench grinder features sealed lubrication bearings in the motor housing, meaning no lubrication is required by the user.

The owner's manual provides detailed instructions for installing tool rests, spark guards, and eye shields, emphasizing the importance of correct installation and adjustment for safety and performance. It also advises on checking for damaged parts and replacing them as necessary. The use of recommended accessories is encouraged, and improper accessories are warned against due to potential injury.
